ALGERNON L. WVILKINSON, OF HUNTSVILLE, ASSIGNOR OF ONE-EIGHTH TO JOHN L.RISON, OF MADISOA COUNTY, ALABAMA.

SASH-HOLDER.

FECIFICATION forming part of Letters Patent No. 314,896, dated March 31;1885.

Application filed October 7,1584.

To all witom it may concern Be itknown that I, ALGERNON L. WILKIN- soN,a citizen of the United States, residing at Huntsville, in the county ofMadison and State of Alabama, have invented certain new and usefulImprovements in Sash-Adjusters, and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it [o appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in sash-holders especially adaptedfor use in railway and street cars, steamboats, omnibuses, and the likewherein a single window or sash is used; but it is, however, capable ofapplication to windows of dwellinghouses, &c.

The invention has for its object the provision of means whereby the sashmay be held at any desired point of elevation, and be practicallynoiseless and free from rattling when in motion or acted upon by thewind.

To these ends the invention consists in the provison of a window-frameof ordinary construction with spring-pressed strips arranged to bear atright angles to each other upon the sides and ends of the sash, andmeans for varying the tension with which the strips press upon the sash,and of guide-pins which are adapted to guide the strips in theirmovement, as hereinafter more fully described, and point- 5 ed out inthe claim. 7

In the d awings, Figure 1 is a front elevation of a window framing andsash of a car, steamboat, &c., having but one sash. Fig. 2 is acentralsection of a window of a dwellinghouse having two sashes. Fig. 3 is acrosssection on the line m w of Fig. 1. Fig. 4 is a front elevation ofthe bead with the springpressed strip removed, and showing thewindow-frame in section. Fig. 5 is a longitudinal section'of a portionof the window-frame. Figs. 6 and 7 are cross and vertical sections,respectively, of the window bead or slat.

Referring to the drawings, in which like letters of reference indicatelike parts in all the figures, A designates a window-frame of ordinaryand well-known construction, and B a window-sash. The sidepieces ofthewindowprovide a bearing for the same.

(No model.)

frame a e provided'with longitudinal recesses a a, in which are placedstrips 0 O, which are pressed normally outward in contact with the sashby means of springs b 0, arranged between the inner wall of the frame Aand said strips 0, as clearly shown in Figs. 2. and 5.

D designates strips or slats secured by screws or otherwise to the innersides of the frame A, near its outer front edge, or removed a shortdistance to the rear thereof, and provided with recesses d d, in whichare placed strips E'E, kept in contact with thesides of the sash B bysprings d d, secured in the recess of said bead. Each of the strips 0and E, which, it will be observed, hear at right angles to etch otherupon the ends or sides of the sash B, respectively, is provided withshort tubes e e, arranged near its upper and lower ends,'and throughwhich pass guide-pins F F, secured to the frame A and slat or head D.The slat D is further provided with ap ertures f, through which projectscrews 9, se-

cured to the strips E, (see Figs. 6 and 7,)

while the strips 0 are provided with apertures 'h and receive screws 2',secured to the frame A, as shown in Figs. 2 and 5.

I attach importance to the guide-pins F and tubes 6 e, as the pins serveto guide the strips in their movement, and the tubes lessen the frictionof the said pins working therein and I also attach importance to thescrews 9, as the tension of the-springs can be increased or decreased bysimply turning the said screws in or out. It will be observed that thescrews also serve to limit the movement of the spring pressed strips.This limiting movement is occasioned by the heads of the screwsimpinging against the tapering walls of the recessed strips and head.

It is obvious that either coiled or flat springs may be used to forcethe strips outwardly, both of which forms of spring are herein shown.

The frameis provided with beads I, arranged on the opposite side of thesash to the slat D, against which the sash bears, as is usual, and maybe constructed similarly to the slat D, but not necessarily so, inasmuchas the sash I00 is amply supported and prevented from rattling by thestrips Gand E, which form essential features of my invention.

The sash may be provided with a button or hook, J, for convenientlyraising it, if desired. v

Modifications in the form and proportion of parts may be made withoutdeparting from the principle or sacrificing the advantages of theinvention, and I would therefore have it understood that I do not limitmyself to the precise construction herein shown.

I am aware that it is not broadly new to provide a sash-holder withspring-pressed strips to bear upon the ends of the sash-frame, nor toprovide a frame and sash with springpressed strips and catches andnotches; but in these devices the sash is subject to a movement at rightangles to its vertical movement, thereby occasioning a rattling noisewhen the sash is elevated which my device overcomes.

It will be understood that when my device car, steamboat, 850., in theform illustrated in with friction-tubes in which said guide-pins areadapted to play, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
